My 98 crown vic makes clicking noises in the locks and the antilock brake light comes on when i turn on the air. is there a short or what?

in the fuse block

The brake lamp fuse in your vehicle protects circuits that not only go to the brake lamps themselves, but also go to the Antilock Brake Controller, the Speed Control Servo, the Shift Lock Actuator, The Hazzard Flasher unit and the multifunction (turn signal) switch. You will need to trace all of the circuits involved to determine where the circuit is shorting to cause the fuse to blow.

What Else Could Be Wrong?

1998 Crown Vic, is it a former police vehicle?

CHECK THE REAR SENSORS AND WIRE.
THEY MAY HAVE BEAN PULLED APART OR RUST IS FOULING THE SENSOR PICKUP.

This is caused by the IAC valve. Over time the valve becomes gummy and inoperative. Get it replaced and the problem is solved. IAC stands for idle air control, hence the stalling concern.

It sounds like "False Antilock Mode" to me. Your Antilock Brake Control Module "thinks" that you have a wheel locking up. This is probably caused by a bad wheel sensor. You need to scan the module to find out which one.

short in something the blinker clicking is the first sign of electrical failure in a car. any questions you can email me at [email protected]

when you depres the brake pedal do yoiu hear a clicking noise in the steering column? (this noise would be a sign of the shift interlock solenoid functioning)? are all of the brake light bulbs working? (it wont let you shift without all brake bulbs working)....you can overide this shift feature by turning key to on position, without starting vehicle, shift into neutral, then into your desired gear. i hope this helpos your some! good luck!

More than likely your Antilock brake siystem going through self test cycle

Your ABS systems use a combination of electronic and hydraulic systems to modulate the brakes individually to prevent them from locking up. ANTILOCK systems consist of wheel speed sensors, a hydraulic control unit (HCU), and an electronic control unit (ECU). Because of how complex the system is your computer does a self-test. If the check is successful, the ANTILOCK and BRAKE lights will go out within a few seconds. If one of the component of the ABS system fails to pass one or both lights will remain lit. One or both warning lights may also come on while driving, also indicating a problem. If just the ANTILOCK warning light comes on, some ABS component has failed, but the car still has hydraulic brakes. The grinding noise could the the ABS pump or your brake pads could to worn to the metal backing and grinding against the brake rotors. I recommend a inspection soon for your safety.
